Description

A kind of chair backrest structure promoting heel row knee space

Technical field

The utility model relates to automotive fields, more particularly to a kind of chair backrest structure for promoting heel row knee space.

Background technique

Currently, knee space is a key feature for influencing riding comfort, it is excellent in the case where seat arrangement determines The design for changing front-row seats backrest is to promote an important means in knee space.Existing chair backrest structure is actually using When have the following problems:

Since existing chair backrest structure is planar structure, so space utilization rate is low, so as to cause knee space compared with Small, the riding comfort of passenger is lower.

Utility model content

The purpose of this utility model is to overcome the deficiencies of above-mentioned background technique, provide a kind of promotion heel row knee space Chair backrest structure.

In order to achieve the goal above, a kind of chair backrest structure for promoting heel row knee space provided by the utility model, It is hung including the transverse direction for vertically hanging tight a steel wire and a lateral arrangement that chair framework, two mounting brackets, two arrange vertically Tight point steel wire；Described two mounting brackets are separately mounted to the two sides of the chair framework, the inside of described two mounting brackets It is respectively equipped with the steel wire mounting leg of indent, two described vertically to hang tight a steel wire and respectively correspond and be mounted on described two installations and prop up On the steel wire mounting leg of frame, the transverse direction hang tight the both ends of a steel wire respectively with two upper ends for vertically hanging tight a steel wire It is connected.

The steel wire that vertically hangs tight for installing indent on chair framework by mounting bracket hangs tight a steel wire with lateral, installs Vertically hang tight a steel wire and laterally hang tight a steel wire and can be provided for seat surface sleeve and hang tight point (install fixed point), in this way due to It vertically hangs tight a steel wire and hangs tight a steel wire laterally as indent arrangement, so the back side of backrest can have more a part of space, To increase knee space, the riding comfort of passenger is improved.

In the above scheme, the cross-brace steel wire of evagination is equipped between two tops for vertically hanging tight a steel wire, The cross-brace steel wire described vertically hang tight a steel wire and is structure as a whole with two.The cross-brace steel wire added can be by seat Surface cover supports, to improve the aesthetic feeling of seat surface sleeve.

In the above scheme, the cross-brace steel wire protrudes the plane where the chair framework back side.

In the above scheme, the transverse direction hangs tight a steel wire and described vertically hang tight a steel wire with two and be generally aligned in the same plane It is interior.

In the above scheme, two lower end bendings respectively inwards for vertically hanging tight a steel wire.By will vertically hang tight The inside bending in lower end of point steel wire, can prevent from vertically hanging tight a steel wire in this way damaging to passenger.

The utility model is compared with the prior art, and sufficiently shows that it is advantageous in that:

1, the vertical of indent is installed to hang tight a steel wire and laterally hang tight a steel wire on chair framework by mounting bracket, is pacified Vertically hanging tight a steel wire and laterally hanging tight a steel wire and can provide for seat surface sleeve for dress hangs tight point (install fixed point), in this way by It is arranged in vertically hanging tight a steel wire and laterally hanging tight a steel wire for indent, so the back side of backrest can have more a part of sky Between, to increase knee space, improve the riding comfort of passenger；

2, the cross-brace steel wire added can support seat surface sleeve, to improve the aesthetic feeling of seat surface sleeve；

3, by the inside bending in the lower end that will vertically hang tight a steel wire, it can prevent from vertically hanging tight a steel wire in this way and passenger is made At injury.

Specific embodiment

The utility model is described in further detail with reference to the accompanying drawings and embodiments, but the embodiment should not be understood For limitations of the present invention.

The present embodiment provides a kind of chair backrest structures for promoting heel row knee space, including chair framework 1, two installation 2, two, bracket arrange vertically vertically hang tight a steel wire 3 and the transverse direction of a lateral arrangement hangs tight a steel wire 4；Described two peaces Dress bracket 2 is mounted on the two sides of the chair framework 1 by rivet respectively, and the inside of described two mounting brackets 2 is respectively equipped with The steel wire mounting leg 2a of indent (using plane where the back side of chair framework 1 as the plane of reference), two described vertically to hang tight a steel Silk 3, which respectively corresponds, to be welded on the steel wire mounting leg 2a of described two mounting brackets 2, and the transverse direction hangs tight the two of a steel wire 4 It is welded respectively with two upper ends for vertically hanging tight a steel wire 3 at end.Indent is installed on chair framework 1 by mounting bracket 2 Vertically hang tight a steel wire 3 and laterally hang tight a steel wire 4, vertically hanging tight a steel wire 3 and laterally hanging tight a steel wire 4 for installation can be Seat surface sleeve offer hangs tight point (i.e. installation fixed point), is so interior due to vertically hanging tight a steel wire 3 and laterally hanging tight a steel wire 4 Recessed arrangement, to increase knee space, improves the seating of passenger so the back side of backrest can have more a part of space Comfort.

Be equipped with evagination between two above-mentioned tops for vertically hanging tight a steel wire 3 (is with plane where the back side of chair framework 1 The plane of reference) cross-brace steel wire 5, the cross-brace steel wire 5 described vertically hang tight a steel wire 3 and is structure as a whole with two. The cross-brace steel wire 5 added can support seat surface sleeve, to improve the aesthetic feeling of seat surface sleeve.The cross-brace Steel wire 5 protrudes the plane where 1 back side of chair framework.

Above-mentioned transverse direction hangs tight a steel wire 4 and described vertically hang tight a steel wire 3 with two and be in the same plane.Two described perpendicular To the lower end bending respectively inwards for hanging tight a steel wire 3.By the inside bending in the lower end that will vertically hang tight a steel wire 3, can prevent in this way A steel wire 3 is only vertically hung tight to damage passenger.

The present embodiment installs vertically hanging tight a steel wire 3 and laterally hanging tight for indent by mounting bracket 2 on chair framework 1 Point steel wire 4, installation vertically hang tight a steel wire 3 and laterally hang tight a steel wire 4 can be provided for seat surface sleeve hang tight point (i.e. installation admittedly Fixed point), in this way due to vertically hanging tight a steel wire 3 and laterally hanging tight a steel wire 4 for indent arrangement, so the back side meeting of backrest A part of space is had more, to increase knee space, improves the riding comfort of passenger.

Meanwhile the cross-brace steel wire 5 added can support seat surface sleeve, to improve the beauty of seat surface sleeve Sense；By the inside bending in the lower end that will vertically hang tight a steel wire 3, it can prevent from vertically hanging tight a steel wire 3 in this way and passenger is caused to hurt Evil.

The above is only the preferred embodiment of the present invention, is not intended to limit the utility model, all practical at this Within novel spirit and principle, any modification, equivalent replacement, improvement and so on should be included in the guarantor of the utility model Within the scope of shield.
